SQL Interfaces in Various Languages

When developing a client application, one or more computer languages will be chosen. The purpose of this section is not to advocate one language 

In each example, a simple SQL statement is used to select rows that match a particular substructure. The rows are then simply fetched and printed. These examples should serve as a starting point to understand how client programs communicate with an RDBMS server using SQL. The examples can also server as a basis for other more complex client programs. 

Selecting rows from a table is only one common operation needed for a client program to work with an RDBMS. In addition to a simple SQL select statement, other more complex select statements will become necessary as more complex client programs are developed. It is also important to see how to properly use the SQL Insert statement. Rather than showing examples in several computer languages, the use of more complex SQL statements is discussed in Chapter 12.
